Enum FrameError 

pub enum FrameError {
    Io(Error),
    TooLarge(u32),
    Varint,
    Decode(Error),
}

Errors produced by the framing helpers. The handler-layer mapping to QUIC application error codes lives in the node crate.

Variants

Io(Error)

The underlying stream failed while reading or writing the frame.

TooLarge(u32)

The length prefix names more bytes than MAX_MESSAGE_SIZE allows. Rejected before anything is buffered.

Varint

The length prefix is not a well-formed varint — a non-terminating continuation run through all five bytes, or a fifth byte overflowing u32. A short or empty buffer reads as truncated, not malformed.

Decode(Error)

The frame’s bytes are not a valid postcard encoding of the expected message.

Trait Implementations

impl Debug for FrameError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FrameError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for FrameError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for FrameError

fn from(source: Error) -> Self

Converts to this type from the input type.
